Job description

Founding Engineer
Full-Stack — Build the platform. Own the stack.

About Runbook

Runbook is building the unified AI operations platform for the physical economy — field services, transportation, retail, and manufacturing. These industries drive $10 trillion in annual economic activity and are finally at an AI inflection point. Runbook's agents replace the manual coordination layer running on emails, spreadsheets, and phone calls at companies that move, make, and deliver physical goods.

Launched November 2025. Already live with enterprise customers and multi-million-dollar deals in late-stage close. The physical economy operates on razor-thin margins — Runbook turns executive AI mandates into measurable revenue and cost impact.

Founder Pedigree Worth Knowing

CEO Obaid Khan co-founded Motive (KeepTruckin) and scaled it from $0 to $500M ARR — then left to tackle an even larger opportunity in the same market. Investors backed this new venture before there was a product or a single customer. CTO Nick Reynolds built engineering teams at Facebook Messenger (pre-IPO), Airbnb, and Discord.

$10T Total Addressable Market

Why This Role

Greenfield Ownership

4 engineers today scaling to ~10. Founding engineers set the technical direction and own the hardest problems end to end — this is not a backlog ticket role.

Real Customer Impact from Day One

Every engineer owns a customer relationship (5–20% of time), gathers requirements directly, and ships platform capabilities that go live in production.

CTO Nick Reynolds built at Facebook Messenger, Airbnb, and Discord. High bar, product-oriented culture, fast feedback loops.

Competitive Comp + Real Equity

$200K–$300K base salary plus 0.2–1% equity in a company with a proven founder and a market-defining opportunity.

The Opportunity

We are looking for a Founding Engineer (Full-Stack) with 3+ years of experience — or 2+ years exclusively at VC-backed startups — who has owned and shipped end-to-end projects at companies with strong engineering cultures.

You should be comfortable working across the entire stack (roughly 70% backend, 30% frontend) with a track record of building consumer or prosumer products with measurable impact. Bonus if you've worked on AI agents, LLM integrations, or automation platforms.

"This isn't a backlog ticket role. Founding engineers set the technical direction, own the hardest problems end to end, and build the platform that will run on hundreds of AI agents for the largest companies in the physical economy."

What You'll Do

• Own features end-to-end from understanding customer requirements to shipping production-ready code; act as a product owner, not a spec-executor


• Work directly with customers (5–20% of your time) to understand workflows, gather requirements, and translate operational needs into platform improvements


• Reverse-engineer customer systems and build integrations with Salesforce, Outlook, TMS, and ERP platforms into Runbook's agentic orchestration layer


• Ship React frontend experiences that make complex AI agent workflows intuitive and delightful for enterprise operations teams


• Collaborate with the founding team (reporting to the CTO) to set technical direction and architectural decisions that define the platform for years to come

Requirements

Required

• 3+ years as a full-stack engineer shipping products across backend and frontend (or 2+ years exclusively at VC-backed startups)


• Experience at FAANG or a faster-paced company (e.g. Databricks, Square) OR a VC-backed startup — early-stage strongly preferred


• Built consumer, prosumer, or internal-facing products with real, measurable user impact


• Owned a medium-to-large project end to end with clear, quantifiable outcomes


• Strong full-stack development skills with proficiency in TypeScript


• Active daily use of AI coding tools — Claude Code, Cursor, or equivalent


• Committed to SF office 5 days/week at 10th & Market (no exceptions)

Nice to Have

• Experience building AI agents, LLM integrations, or automation platforms


• Familiarity with LLMs, prompt engineering, or AI tooling (Langchain, etc.)


• Experience integrating enterprise APIs, ERPs, or complex third-party systems


• Degree from a top-20 CS program

Traits to Avoid

• Most recent experience at a legacy software company (IBM, Visa, Oracle, Cisco) or doing tech inside a non-tech company (e.g. AI at a hospital)


• Lifer at a single large company for 10+ years with zero startup exposure


• Multiple sub-one-year stints without a clear explanation


• Needs direction or defined scope to be productive — this role requires self-driven ownership


• Prefers backend-only or frontend-only work — full-stack ownership is non-negotiable

Technology Stack

TypeScript Node.js React Python AWS LLMs Agentic Systems ERP / API Integrations Salesforce Temporal / Inngest

Interview Process

1

2

Technical Interview

Deep-dive with the CTO on full-stack experience, product ownership, architectural decisions, and how you've driven measurable outcomes.

3
